Multifragmentation: thermal vs. dynamic effects Conference Paper uri icon


  • Reactions of 1.8 - 4.8 GeV 3He, 5.0 - 9.2 GeV/c - and 6.0 - 14.6 GeV/c protons with natAg and 197Au targets have been studied with the ISiS 4 detector array. From reconstructed events, excitation-energy distributions have been determined and combined with a 2,3H/3,4He isotope-ratio thermometer to study the heating curve for the thermal-like component of these reactions. Dynamic effects also manifest themselves in the data, as evidenced by deposition-energy saturation above 5 GeV, IMF emission during expansion, and sideways peaking of the IMF angular distributions for beam energies Eb 10 GeV.
